STROPPER FOR RAZORBLDES.

Specification of Letters Patent.

Application filed. October 9, 1908. Serial No. 456,971.

To cZZ whom it 'may concern:

Be it known that we, Hanny GoLnsMiTi-I and SAMUEL WERNER, citizens oft-he United States, residing at Chicago, in the county of Cook and Stateof Illinois, have invented certain new and useful Improvements inStroppers for Razor-Blades, of which the following is a specification.

This invention relates to improvements in a device or aipliance to beused for stropping razor-b ades and other instruments which require verysharp edges, and while it is more especially intended for holding` andstropping blades of safety-razors of various makes, yet it is, withslight changes, applicable for use in stropping or sharpening the bladesof ordinary razors, or other kinds of blades, and it consists in certainpeculiarities of the construction, novel arrangement, and operation ofthe various parts thereof, as will be hereinafter more fully set forthand specifically claimed.

The principal object of the invention is to provide a stropper forrazor-blades and the ike which shall be simple and inexpensive inconstruction, strong, durable and efficient in operation, and so madethat the stropping or sharpening operation may be successfully andproperly performed byl an unskilled erson and without injury to theblade or c anger of cutting the hands of the operator.

Another object of the invention is to rovide a simple and eilicientholder for the blades, to be used in. connection with the rotarystropper, and which forms a part of the invention.

Other objects and advantages of the invention will be disclosed in thesubjoined description and explanation.

In order to enable others skilled in the art to which our inventionpertains, to make and use the same, we will now proceed to describe it,referring to the accompanying drawing, in Which- Figure 1 is a centralvertical sectional view through the rotary strop er and frame therefor,showing a razorb ade held in stropping position thereon by means of ablade-holder embodying one of the forms of said holders, Fig. 2 is afragmental view in elevation of the upper portion of one side of thesupporting-frame for the rotary stropper, showing by dotted lines thenormal position thereon of one of the blade-holders; Fig. 3 is a planview of a blade-holder embodying one form of the invention therein; Fig.L1 is a similar view of a bladeeholder, showing a modiiication in. theconstruction thereof Fig. 5 .is a cross-sectional View thereof taken online 5 5 of Fig. 4 looking iii the direction indicated by the arrows gFig. is a plan view of still another modified form of the blade-holder;and Fig. 7 is a crossesectional view thereof taken on line 7-7 of Fig. 6looking in the direction indicated by the arrows.

Like numerals of reference, refer to correspending parts throughout thedifferent views of the drawing.

The reference numeral 10 designates a cylindrical roller which may bemade of any suitable size and material, but usually of wood, and has itseriphery covered or provided with suitabfe stro ping material 11, suchas leather. The rol er or rotary strop per 10 is centrally mounted on ashaft 12 which is horizontally `iournaled at its ends in uprights 13located at each end of a base 14 which uprights and base constitute thesupporting-frame for the rotary part of the sti-opper. One end of theshaft 12 is provided with a crank-handle 15 by means of which the roller10 may be turned. he upper end of each of the uprights 13 of thesuportingframe is provided with a horizontally cisposed recess 16 whichextends from one of the edges thereof inwardly and has its floor orbottom rounded or downwardly and inwardly curved at its inner portion asis clearly shown at 17 in Figs. 1 and 2 of the drawing. Secured to theupper end of each of the u rights 13 is a spring 18 which are extenderover the rounded or cutaway portion 17, and together with said partsproduce the recesses 16 which are for the reception and operation oflateral and i'lat enten sions 19 with which the blade-holder is proevided at each of its ends.

Referring now to Figs. 1 and 3 of the drawing, the blade-holder consistsof a flat body portion 20 which is preferably rectangular in shape andof any suitable size and material, and has at each of its ends a llatextension 19 to vlit and operate in the :recesses 16 of thesupporting-frame, as before stated. The body 20 is provided on one ofits surfaces near one `of its edges with two spaced apart ins 21 to litin corres ondingly spaced openings 22 in the razor-b ade 23 which isshown in Figs. 1 and 3 of the drawing as being of that type known as theGillette blade.

Located on the opposite edge of the body 2O is a clamp 211 which isprovided. at about the middle of its outer portion with an extension 25to be used in tilting the holder to the position shown in Fig. 1 duringthe operation of stropping the blade. This clamp preferably has its freeedOes outturned as at 26 to cause it to readily pass over the inner edgeof the blade 23, and its members are su'lliciently separated to permitof the reception oi the body 20 and a portion ol the blade 23, yet so asto hold the two firmly together.

ln Figs. 4l and 5 is shown a modification in the construction oi theholder which consists in forming the body portion. 2Oa thereol withlateral extensions 19 at its ends and with a tilting extension. 25 atabout the middle of one of' its edges. The lower portion of each end ofthe body 2Oa in the modii'ication now under consideration is providedwith an inturned llange 27 which have their edges spaced a slightdistance from the upper surface oi' the body 20a and are inclined towardeach other at their lower ends as is clearly shown in Fig. l of thedrawing, so that the blade may be inserted downwardly between the twoflanges andv body where it will be securely held with its lower edgeextended far enough below the lower edge ot the body 2()EL to contactwith the stropping material 11 on the roller when tilted for thestropping operation.

ln Figs. 6 and 7 is shown another modi'lication in the construction olthe bladeholder which consists in Aforming the tilting extension 25 andlateral extensions 19 of a single piece, and placing thereon a clamp245L which is provided with a central opening 28 at the middle oi itsupper edge through which the extension 25 is passed. ln this latterconstruction the parallel members 2Q of the clamp 24;EL are spaced apartsulliciently to permit of the insertion therebetween ol the razor-bladewhich will be held in such position by means oi the clamping action oi'the members 29 of said clamp.

From the foregoing and by reference to the drawing it will be clearlyseen and readily understood that by placing the extensions 1) of any oneof the blade-holders above-described within the recesses 16 between thesprings 18 and the top oi" the cutaway parts of the uprights 13 theholder will be retained by the action olf-said springs in substantiallya horizontal position, as shown by dotted lines in Fig. 2, and so thatthe blade carried by the holder will be out of contact with thestropping material 11 on the rotary cylinder or roller. Vilhcn it isdesired to strop or sharpen the blade the holder may be tilted by meansof one hand of the operator to the position shown in Fig. 1 while therotary stropper may be turned with the other hand applied i cease-5 tothe crank-handle 15 on one end of the shalt oi the roller. As theextensions 19 are ilat, it is apparent that they will rock on therounded portion 17 of the uprights so that their lower edges will extendinto the downwardly and inwardly inclined portions of the recesses 16while their upper edges will rest against the lower surfaces of' thesprings 18 as long as tilting pressure is applied to the holder, whichmay be done by applying` the hand to the tilting extension 25 andbladeclamp or the body of the holder. As soon as the hand is removedfrom the holder, it is apparent that the springs 18 will press the upperedges of the extensions 19 downwardly, and thus remove the blade fromthe rotary stropper.

lf it is desired to use the holder shown in Figs. 1 and 3 ci the drawingfor other blades than that of the Gillette type or without holes, it isapparent that the holder may be turned over from the position shown inFig. 1 and the blade placed on the surface thereof opposite that havingthe pins thereon where it will be held by means oi' the clamp.

Having thus fully described our invention, what we claim as new, anddesire to secure by Letters-Patent, is-- 1. The combination with twospaced apart uprights, oi a stropping roller ournaled therebetween, aspring secured on the upper end of each of said uprights and extendedslightly above a portion of the upper end of each or the saine, and ablade-holder having at each of its ends an extension adapted to beinserted between the said springs and upper parts of said uprights.

2. rl`he combination with two spaced apart uprights, of a s'troppingroller ournaled therebetween, means to turn the roller, a spring securedon the upper end of each of said uprights and extended slightly above aportion. of the upper end of each of the same, a blade-holder consistingof a body portion having at each oiI its ends an extension adapted to beinserted between the said springs and upper parts of said uprights, andmeans on the body portion oi the holder to hold a blade in positionthereon.

3. T he combination with two spaced apart uprights having their upperends formed with an inwardly and downwardly inclined cutaway part, aspring secured on the upper end of each of said uprights and extendedover said cutaway portions, and a bladeholder having at each of its endsan extension adapted to be inserted between said springs and the uppersurfaces of the cutaway part ci the uprights.
